About

Hydrotopoly

Features
Read full description

Hydrotopoly is a calm, offline guide to growing your first hydroponic basil using the simple, pump-free Kratky method. • Nine short lessons that move at the plant's pace, from setup to first harvest. • A private journal for your own notes and optional pH, EC and reservoir readings — stored only on your device. • Simple progress tracking with clear, milestone-based steps instead of rigid countdowns. • No account, no ads, no analytics, and no connected sensors. Hydrotopoly is an educational and journaling tool. It does not diagnose plants, verify food safety, or replace the instructions supplied with your seeds, nutrients and equipment. Lessons cite trusted public sources and always defer product-specific steps to your own product labels and safety information.
